The present disclosure provides a touch display panel, a display device, and a drive method. The touch display panel includes a substrate, a plurality of touch sensing electrodes, and a plurality of pressure sensors. The substrate is provided with a light emission side; and a plurality of touch sensing electrodes and a plurality of pressure sensors. The pressure sensors and the touch sensing electrodes are positioned at the light emission side of the substrate. The pressure sensor includes a first pressure electrode and a second pressure electrode. The first pressure electrode is formed on the display panel. The second pressure electrode and the touch sensing electrode jointly form a touch circuit, and the second pressure electrode is used as a drive electrode of the touch circuit.
